Abstract

In this paper we want to show how the development of Edmund Husserl’s thinking led him to propose the concept of Life-World in Crisis. Then we highlight the relationship of this concept with the positive sciences and how it intends a priority that underlies and gives meaning to the formers. We point out how Life-World is constitutes by transcendental reduction and how this is cause of tensions with other issues of Husserl's philosophy. Analyzing the concept of world in Being and Time by Martin Heidegger, we make a comparative discussion with some features of the Life-World especially in the transcendental foundation contrasted with an hermeneutics of Dasein, the understanding of temporality in each authors and the relationship between theory and praxis in the first approach to reality.
